Abstract

In transformational grammar the notion of a chain has been central ever since its introduction in the early 80's. However, an insightful theory of chains has hitherto been missing. This paper develops such a theory of chains. Though it is applicable to virtually all chains, we shall focus on movement-induced chains. It will become apparent that chains are far from innocuous. A proper formulation of the structures and algorithms involved is quite a demanding task. Furthermore, we shall show that it is possible to define structures in which the notion of a chain coincides with that of a constituent, so that the notion of a chain becomes redundant, generally without making the theory more complicated. These structures avoid some of the problems that beset the standard structures (such as unbound traces created by remnant movement).
